T0 all whom t may concern Be it known that I, CHARLES D. REYIIoLDs, acitizen of the United States, residingv at Gretna, in the county Stateof Virginia, have invented a new and useful Flue-Support, of which/thefollowing is a specification.

vThe subject ofthe flue support intended for supporting flues in tobaccocuring houses and for like purposes.

or houses are built and provided with suitable fire boxes froml whichthe flues lead. These flues-are constructed of sections of stove pipingand extend through the curing house slightly/above the floor thereof.These flues,y after passing through the. house, are conducted throughsuitable openings in the Side of the house so th bustion may bedischarged without the house and be dissipated in the atmosphere.

Where a number of curing houses are erected it is customary, to save thecost of equipping each separate house with a flue or flues, to move theflues from house to house as occasion demands. As these flues are ratherlong, and slant upwardly from the floor to the opening through whichthey are conducted to the outer air, it becomes necessary to prop 'orsupport the flues by some means and, 1n the majority of cases, a woodenprop is resorted to often causing loss through fire.

The invention contemplates providing a prop which may be adjusted tomeet the different conditions of different curing houses.

The invention also contemplates providing means for locking the fluesections together at the point of support, thus preventing the flue fromsloping to each side of the support and probably pulling apart.

A further object of the invention is the production of a simple, durableand efficient in the scope of what is claimed without departing from thespirit of the invention.

-of Pittsylvania and present invention is a- For the purpose of curingtobacco, sheds at thegases of com' invention resides in the com-- f 'Apractlcal embodiment of the invention 1s shown in the accompanyingdrawing,-

wherein: -y l Figure l Isa vlew in side elevation of a 'Supportconstructedvinv accordance with the lnve'ntion, a fragment of a fluebeing shown;

Fig. 1s a'vlew partly in elevation and partlylin. sectlon on the line2-2 of Fig. 1.

Referrmg to the drawing by numerals of reference lIn carrying out theinvention there is prov1ded a base or foot l from which rises thetubular supporting member 2 having an aperture 2"in its wall to permitthe end of a pawl 3 to enter the tubular member 2. While the pawl may beof any suitable formation, 1t Ishereln shown as consisting of a bentresilient strip which is secured to the outer surface of the member 2 bya screw 4 or otherwise.

A rod 6 is slidablewithin the tube 2 and has formed longitudinallythereof 'a rack having teeth 5 vwhich are adapted to be engaged by thepawl 3 so that the rod may be adjusted to various positions with respectt0 themember 2 thus to shorten or lengthen the support.

The rod 6 merges into a head formed with oppositely extending arcuatearms 7 whlch are adapted to support and partially encircle the flue.Opposed pins 8 extend through apertures formed. in the arms 7 and areadapted to pierce the metal of the flue 9 at that portion of the fluewhere sections' telescope. These pins 8 may be secured to the arms 7 inany desired manner but are here shown as forming the ends of screws 8which are threaded into the arms 7 and which may be threaded in or outto project ythe pins inwardly to pierce the flue or draw them outwardlyto release the flue from the support.

Also, it will be noted particularly ofwFig. 2 that the pins 8 aresmaller than the screws 8 and by reason of the screws 8', the taperedpins may be forced under great pressure to penetrate the overlapping ortelescopic ends of the pipes so as to pierce or penetrate the same andnot merely to indent thev pipes. In addition, shoulders are formedfacing inwardly at lthe juncture of the pins and screws, sov as to sealthe openin s around the pins. t is thought that the operation of thedevice will be thoroughly and fully underratentea Junei, 192e.

` out a 4of uniform diameter engaged stood from the -foregoingdescription withspecial and detailed explanation thereof.` i

Having thus described the invention, what is claimed as new and soughtby Letters Patent, is Y 1. In a flue support, an arcuate pipe receivingportion providing oppositely branch- 'ing arms and formed with adownwardly eX- tending standard suitably supported from a'floor, one ofsaid arms being provided with a threaded opening therethrough and saidarms at said supporting portion being designed to receive telescopic endportions of two interlitting pipes forming a flue, a screw in ysaidthreaded opening and formed with an abruptly reduced inner portionforming a' pin having its inner end sharply tapered to pierce theoverlapping portions of the pipe upon the screw' being turned inwardlyso as to hold said pipe sections against turning or separation, orlongitudinal movement one with respect to the other, the aperture aroundthe pin, constituting the reduced portions of the screws, being closedby the adto their free ends and having abruptly re.

duced pins tapered at their inner ends adapt-- ed to penetrate saidoverlapping portions and inwardly facing shoulders formed at thejuncture of the screws and pins adaptedto seal the openings around thepins in the overlapping portions of the pipe sections through which thepins pass, said pipe sections being thereby held against separation orturning. In testimony that I claim the foregoing as my own, I havehereto affixed my signature in the resence of two witnesses.
